Wi-Fi Overview
Wi-Fi, based on IEEE 802.11 standards, enables wireless data exchange through radio waves. It is prevalent in homes, offices, and public spaces, with over 3.05 billion Wi-Fi-enabled devices shipped annually. The Wi-Fi Alliance manages the trademark and certification process, ensuring compliance with IEEE standards and security protocols. Wi-Fi operates in the 2.4GHz and 5GHz bands, with newer versions exploring the 6GHz spectrum for enhanced speeds up to 9.6Gbit/s.
Wi-Fi supports local network and Internet access, with coverage ranging from small areas to large square kilometers. It is widely used in hotspots, routers, and city-wide networks like those in Mysore and St. Cloud. Wi-Fi stations communicate through data packets using unique MAC addresses, shared channels, and modulation techniques. Wi-Fi optimization includes positioning systems for device location, signal strength measurements, and interference management for optimal network performance.
Overall, Wi-Fi technology continues to evolve with improved speed, coverage, and efficiency, making it an essential part of modern connectivity solutions in various settings.
